Does a Held-to-Maturity Strategy Impede Effective Portfolio Diversification for Islamic Bond (Sukuk) Portfolios? A Multi-Scale Continuous Wavelet Correlation Analysis

There is a critical gap in the literature in studying the portfolio diversification opportunities available to sukuk investors and evaluating these in light of held-to-maturity strategies usually adopted by these investors. This article has made an initial attempt to study the portfolio diversification strategies for sukuk portfolios across heterogeneous investment horizons. Our findings critically indicate that returns between local currency sukuk in different markets generally have low levels of correlations across different investor holding periods, thus enabling both short and long-run portfolio diversification benefits. However, in contrast, international currency sukuk issued in different markets exhibits high levels of correlations in the longer-term investor holding periods. Also, in the domestic market context, returns on different classes of domestic sukuk are found to exhibit strong correlations in the longer-holding periods. Our findings critically highlight the feasibility of held-to-maturity sukuk investment strategies from a portfolio diversification perspective.     

Injury care in low- and middle-income countries: identifying potential for change

The epidemiologic, demographic, and socio-political transitions underway in many low- and middle-income countries (LMIC) are associated with a substantial burden of disease due to injuries. LMIC have devoted relatively little attention to the injury problem. This paper argues that whereas prevention remains paramount, improving health care services for injuries will also contribute to reducing the burden. It examines the reasons for the relative inaction in LMIC to date, and contrasts this to high-income countries (HIC) which have seen substantial falls in mortality from improved trauma care systems. Mortality data, although readily available, are the tip of the clinical iceberg and there is a need for better-quality hospital data that can be used to monitor any future improvements. Models of trauma care from HIC are reviewed. It is suggested that the greatest potential for improvement can be achieved if entire trauma systems are improved, including pre-hospital, hospital and rehabilitation care. LMIC may not be able to afford the whole system and improving the most sensitive components of the system may be a better option. Models of trauma care developed in HIC need careful consideration to determine their effectiveness, appropriateness, affordability and equity implications for LMIC. Imports of blueprints from elsewhere are likely to fail; context sensitive and appropriate policies need to be developed locally through a consultative process. Effective working needs to be across disciplines, involving consultation with stakeholders, and requires investment in education, training and equipment. The evidence base for trauma services in LMIC is almost non-existent, highlighting the urgent need for research in these settings.     

Price volatility and the political economy of resource-rich nations

This paper attempts to understand how price volatility affects the political transition of a resource-rich nation. Two states reflect price volatility: ‘high prices’ and ‘low prices’. We argue that whether or not political transition (i.e., a switch from one regime to another) will take place in a particular state depends critically on the kind of goods a country produces. If the main economic activity in a country is the extraction of “point-source” resources such as oil that demands capital-intensive production, the opportunity cost of switching the existing regime does not alter if the price of the resource changes but the benefit becomes more lucrative. Therefore, the incumbent group is most vulnerable during ‘high prices’. If the main economic activity of the nations is the production of “diffused resources” such as coffee that requires labor, prices do affect the opportunity cost. Nations concentrating in these commodities face acute political crisis during downturns.     

Designing corporate brand experience in an online context: A qualitative insight

This study explores the dimensions and components of corporate brand experience in an Internet setting. Corporate brand experience (CBE), which is a source of a company's added value, could be an effective way to position a corporate brand in relation to the overall corporate marketing strategy. However, the concept of CBE has attracted very little attention from previous research, thereby our understanding of what the concept is and how to operationalize it is limited. Previous brand experience research is mainly focused on the conceptual understanding of brand experience itself, and/or the product brand level (rather than at corporation level). Understanding CBE is important because corporate brand equity (e.g. corporate image, brand loyalty) is dependent not only on how one is satisfied with the product (mostly addressed by functional/performance values of product), but also through the values of the corporation (corporate brand values). This study thus contributes theoretically to the corporate and online branding literature by proposing underlying new dimensions and components of CBE in an online environment. A series of focus group discussions (FGDs) with 32 online banking respondents informs the study. We identify five main themes and 26 sub-themes of corporate brand experience — corporate visual identity, functionality, emotional, lifestyle and corporate/self-identity. Financial service providers can address these dimensionalities during the process of brand positioning and when designing their corporate marketing in an online setting.     

Exchange-rate variability and industry trade flows between Malaysia and Japan

This research investigates the exchange-rate risk sensitivity of Malaysian bilateral trade flows with its important trading partner, Japan. To this end, bounds testing approach to co-integration is applied using industry level data over the monthly period 2000–2013. Findings suggest that above the one-third of the total co-integrated export (43.86%) and import (34.54%), industries experiences the ringgit/yen variability effect in the short run. However, this effect sustains in relatively less number of export (14.03%) and import (32.73%) industries in the long run. It is interesting to note that exchange-rate risk boosts trade flows in the majority of these affected industries.     

Online grocery shopping: the impact of shopping frequency on perceived risk

Online grocery shopping has enjoyed strong growth and it is predicted this channel will continue to grow exponentially in the coming years. While online shopping has attracted an abundance of research interest, examinations of online grocery shopping behaviour are only now emerging. Shopping online for groceries differs considerably from general online shopping due to the perishability and variability of the product, and frequency of the shopping activity. Two salient gaps underpin this research into online grocery shopping. This study responds to calls to investigate the online shoppers’ experience in the context of online purchasing frequency. Second, this study examines the mediating effect of perceived risk between trust and online repurchase intention of groceries. An online survey was employed to collect data from shoppers who were recruited from a multi-channel grocery e-retailer’s database. The online survey, comprising 16 reflective validated scale items, was sent to 555 frequent and infrequent online grocery shoppers. Results find that while customer satisfaction predicts trust for both infrequent and frequent online grocery shoppers, perceived risk fully mediates the effect of trust on repurchase intentions for infrequent online grocery shoppers. Furthermore, path analysis reveals that the developed behavioural model is variant across both groups of shoppers. Theoretically, we provide a deeper understanding of the online customer experience, while gaining insight into two shopper segments identified as being important to grocery e-retailers. For managers, this study tests an online customer behavioural model with actual purchasing behaviour and identifies the continued presence of perceived risk in grocery e-retailing, regardless of purchase frequency or experience.     

Tackling one-sidedness in equality and diversity research: Characteristics of the current dominant approach to managing diverse workgroups in Iran

The primary aim of this paper is to investigate whether equal opportunity and diversity pronouncements, both internally through organizations’ own administrative policies or externally through imposed governmental legislations, benefit those who are the main subject of such initiatives (i.e., employees). While a majority of current research on equality and diversity has been dominated by writings on developed and specifically Western nations, this paper tackles such one-sidedness in previous research and takes the current understanding further by providing employee perspectives on equality and diversity in employment to encompass less developed nations with a particular focus on Iran. Using a qualitative research approach data were collected from employees across two construction and manufacturing industries. Based on the analysis of the data, we found, first, shared religious beliefs and language to be envisaged as playing a crucial part in establishing the ethnic minority workers’ affiliation to a workgroup; second, the prospects for implementing declared equality and diversity polices to fade away as the employee began to work; and third, the adoption of diversity and equality policies to be primarily driven by (1) the dire state of the economy, and (2) the need for a mechanism to fit only the management priorities.     

Transmission channels matter: Identifying spillovers from FDI

The empirical literature on the spillovers of foreign direct investment (FDI) has so far not analysed the well-established theoretical transmission channels through which FDI impacts on domestic firms. This paper shows how channels of transmission matter for productivity spillovers from FDI by providing more fuller and nuanced picture of the effects. We analyse a panel of eight sub-Saharan Africa countries spanning the period 2006–2014 and demonstrate the empirical relevance of distinguishing three channels – demonstration, labour mobility, and competition. We provide measures of these effects and also show that the size, significance, and sign of spillover effects depend on the local absorptive capacity, technology levels, geographical proximity, and foreign ownership structure. Overall, results suggest that demonstration spillovers are large and economically significant, whereas the patterns of labour mobility and competition spillovers are not stable across the various specifications and measures. Finally, the analysis involves several measures of further investigations and robustness checks. Results are robust to the construction of spillover and outcome variables, the introduction of additional explanatory variables and an alternative estimation method.     

Social Media and Purchasing Behavior: A Study of the Mediating Effect of Customer Relationships

Overwhelmed by the use of social media in augmenting human interactions, researchers have developed special interest in understanding the use of social media in developing strong and customized relationships with customers. In line with this, the current study aims to explore the impact of social media on purchasing behavior with mediating effect of customer relationship. The findings indicate that majority of the respondents use social media for purchasing purpose and there is a positive relation between social media and customer relationship, as well as social media and purchasing behavior, with customer relationships fully mediating and enhancing the relationship between social media and purchasing behavior. It has been also found that the majority of the respondents use social media for purchasing purposes. This study offers new insights into the conceptual development and understanding of social media in enhancing customer relationships and affecting purchasing behavior. The study acts as a strong support and aid towards developing and managing global customer relationships through the use of social media.     

The product life cycle and sample representativity bias in price indexes

Official price indexes are usually calculated using matched samples of products. If products exhibit systematic price trends at different points in their life cycle then matched sample methods may introduce bias if the life cycle movement in the sample does not adequately reflect that in the population. This article explores the extent of these life cycle pricing effects and then examines the bias it can introduce in measured inflation. A large US supermarket scanner data set for six cities and six products over 12 years is used. Using hedonic methods we find that the life cycle component of price change is important across a range of products and cities. To explore the bias introduced by these movements, we use simulations that construct indexes with different sample update frequency. For indexes that are never completely resampled, we find an annual absolute bias of 0.88 and 0.59 percentage points depending upon whether we use the actual prices or prices imputed from our hedonic model. This compares with absolute biases of 0.34 and 0.10 percentage points for the corresponding cases for samples, which are re-selected annually. Thus our results provide strong support for more frequently updating index samples.
